NCT02434718

Brief Summary

The primary objective of the study is to evaluate the safety and tolerability of single and multiple intravenous (IV) infusions of Aducanumab in Japanese participants with mild to moderate Alzheimer's Disease (AD). The secondary objectives of this study are as follows: To evaluate the serum pharmacokinetics (PK) of Aducanumab after single and multiple intravenous (IV) infusions of Aducanumab; To evaluate the effect of single and multiple IV infusions of Aducanumab on immunogenicity.

You may qualify if:

  • Must be ambulatory
  • Must have a clinical diagnosis of mild to moderate AD
  • Must be in good health as determined by the Investigator, based on medical history and Screening assessments
  • Must have a caregiver who, understands the study and assents to accompany the subject to all study site visits, provide information to the Investigator/study site staff, specifically about cognitive abilities and AEs/SAEs and return for per-protocol follow-up visits and procedures
  • Must consent to blood sample collection for deoxyribonucleic acid (DNA; genotyping) and ribonucleic acid (RNA; for potential future analysis).

You may not qualify if:
